2. Safety
2.1 Safety rules
To avoid property damage and personal injury, the following rules shall be followed when
working on the hazardous live parts of the battery energy storage system:
• It is available for use.
• Ensure that it will not restart.
• Make sure there is no voltage.
• Grounding protection and short circuit protection.
•Cover or shield adjacent live parts.

9
2.2 Safety information
Part damage or short circuit may cause electric shock and death. A short circuit can be caused by
connecting battery terminals, resulting in current flow. This type of short circuit shall be avoided
under any circumstances. For this reason, follow these instructions:
• Use insulated tools and gloves.
• Do not put any tools or metal parts on the battery module or high-voltage control box.
• When operating the battery, be sure to remove watches, rings, and other metal objects.
• Do not install or operate this system in explosive or high-humidity areas.
• When working on the energy storage system, first turn off the charging controller, then the
battery, and ensure that they are not turned on again.
Improper use of the battery energy storage system can lead to death. The use of the battery
energy storage system beyond its intended use is not allowed, because it may cause great danger.
Improper handling of the battery energy storage system can cause life-threatening risks, serious
injury or even death.
Warning! Improper use can cause damage to the battery cell.
• Do not expose the battery module to rain or soak it in liquid.
• Do not expose the battery module to a corrosive environment (such as ammonia and salt).
• The battery energy storage system shall be debugged no later than six months after delivery.
3. Transport to the end customers
3.1 Provisions on Shipping of Battery Modules:
It is necessary to comply with the relevant regulations and provisions on roads for shipping
lithium-ion products in the corresponding countries.
It is prohibited to smoke in the vehicle during transportation or in the vicinity during
loading and unloading.

10
The dangerous goods transport vehicles shall meet relevant regulations concerning road
transportation and shall be equipped with two tested CO2fire extinguishers.
It is forbidden for the freight forwarder to open the outer package of the battery module.
Use only approved lifting equipment to move the battery cabinet system. Use only the hanging
lug on the top of the battery cabinet as the connection point. When lifting, the angle of the sling
must be at least 60°.
Improper vehicle transportation can cause injury. Improper transportation or improper
transportation locks may cause the load to slip or overturn, resulting in injury. The cabinet shall
be placed vertically to prevent it from sliding in the vehicle, and a fixing belt shall be used.
A tilting of the battery rack may cause injury. The maximum weight of a single battery
rack of BOS-GL can reach 51 kg. When tilted, they may overturn, causing injury and damage.
Ensure that the battery cabinet is on a stable surface and that it does not tilt due to load or force.
The battery energy storage system can be damaged, if not properly transported. The
battery module can only be transported vertically. Note that these parts may be top-heavy.
Failure to follow this instruction may result in damage to the part.
During transportation, the battery storage rack may be damaged when it is installed with
the battery module. The battery storage rack is not designed to be transported with the installed
battery modules. Always transport the battery module and the battery rack separately. Once the
battery module is installed, do not move the battery rack, and do not lift it by a lifting device.
If possible, do not remove the transport packaging before arrival at the installation site.
Before removing the transport protector, check if the transport packaging is damaged, and check
the impact indicator on the outer packaging of the battery converter. If the impact indicator is
triggered, the possibility of transport damage cannot be ruled out.
Improper transportation of battery modules may cause injury. The single battery module
weighs 44 kg. If it falls or slips, it may cause injury. Only use suitable transport and lifting
equipment to ensure safe transport.

11
Wear safety shoes to avoid the danger of injury. When transporting the battery rack and
battery module, their parts may be crushed due to their heavy weight. Therefore, all persons
involved in transportation must wear safety shoes with toe caps. Please observe the safety
regulations for transportation at the end customer's site, especially during loading and unloading.
During transportation and installation of unpacked battery storage cabinets, the risk of
injury increases, especially on sharp metal panels. Therefore, all personnel involved in
transportation and installation must wear protective gloves.
The maximum weight of a single rack of BOS-GL can reach 51 kg. We suggest that at least
2-3 people work together to install the battery rack. The lifting device is helpful for heavy parts,
and the pulley or cart for light parts. Be careful not to damage the case. The number of battery
modules stacked shall not be more than 12.
Check whether the delivery is complete.
3.2 Permissible and Impermissible Storage Positions of a Packaged
Battery Module
The battery module can only be transported in an upright position. Please note that the battery
rack may be very top-heavy.

5.4.2 Installation of Rack
①Take out two side beams and top and bottom beams and assemble them into a rectangular
frame, connect the two top beams with the side beams, and then fix the side beams and top
beams with the round head hexagon combination screws and hexagonal wrench. After fixing,
take two bottom beams and connect the side beams, and fix the side beams and bottom beams
with the round head hexagon socket combination screws and hexagonal wrench.
②The left and right diagonal braces are fixed on both sides of the beam with round head
hexagon combination screws and hexagon wrenches.
③Fix the two left base plate units to the lower left and upper right corners of the lower rack
using the round head hexagon socket combination screws and hexagonal wrench. Similarly, fix
the two right base plate units to the upper left and lower right corners of the lower rack using the
roundhead hexagon combination screws and the hexagonal wrench.
④Screw the base into the bottom plate and secure it with hexagonal wrench or by hand.
⑤ When installation is complete, stand the rack up.
⑥To fix the rack on the wall, use a hexagonal wrench to install the rack fastener on the socket
combination screw hole above the rack and fix it with the socket combination screw. Fix the
other side of the rack with the wall using round head hexagon combination screws. To fix two
racks together, install the rack fasteners on the hexagon socket combination screw holes above
the frame, and fix them together with hexagon socket combination screws and nuts.
